General information about the structure of the inductor, its operating logic, where it is used, its types, the basic function and symbol in the circuit are given. The unit of the coil is Henry and is represented by the letter L in the circuit. A coil is a circuit element produced by winding a conductive wire on top of each other or side by side.
When AC current is applied to the coil, a magnetic field is formed around the coil because the direction of the current changes continuously. Since this magnetic field shows an additional resistance to current, the resistance of the coil to the current increases in AC circuits. In DC circuits, the resistance of the coil to the current is the ohmic resistance caused by the metal from which the coil is produced.
The part on which the coils are wound is called spool, drill chuck or carcass, and one turn on the conductive chuck is called spir, turn or winding. Coil windings are usually used with varnished (insulated) copper wire.
Inductance is the degree to which the coil is self-affecting. The inductance unit is Henry. A henry is the amount that corresponds to the inductance of this coil if the change in AC current of 1 A passing through the coil in 1 second produces an opposite electromotive force (EMF) of 1 volt. Since Henry corresponds to a very high value in terms of inductance, henry's undercoats are often used in applications.
What is Coil, Coil Types The similarity between coils and capacitors is that both circuit elements are reactive circuit elements that do not consume electrical energy. Capacitors can store the electrical charge as well as the coils store the electrical energy as a magnetic field for a short time. The important difference between these two circuit elements; it is the voltage shift of the coils forward while releasing the voltage back (phase difference) while the capacitors are connected to the circuit. The phase difference between the voltage and current caused by the coil and capacitors causes different benefits and damages in applications.
